Disassembly and Reassembly  
Referring to Figure 1, disassemble the Meter as follows. A  
Phillips-head screwdriver and small flat-blade screwdriver  
are required.  
Cleaning  
W Warning  
To avoid electrical shock, remove test leads  
and any input signals before cleaning.  
1. Remove the test leads and set the rotary knob to OFF.  
2. Remove the Phillips-head screws from the case bottom.  
3. Separate the case top from the case bottom.  
To clean the case, wipe it with a cloth lightly dampened with  
water and a mild detergent. Do not use abrasives, solvents,  
or alcohol.  
4. To replace the battery: lift the battery from the case  
bottom and insert a new 9V battery. Be sure the positive  
and negative battery posts are oriented correctly.  
Recommended Test Equipment  
A list of recommended equipment for the performance test  
and calibration adjustment procedure is shown in Table 2.  
5. To remove the pca: insert a small, flat-blade  
screwdriver between the edge of the case top and the  
pca where shown in Figure 2. Gently unsnap a side of  
the case top from the pca. Repeat on the other side of  
the pca. Unsnap the case from the top of the pca last.

7. Set the 5700A using the input voltage shown in Table  
4. The reading on the display should be within the  
values shown in Table 4.  
Performance Test  
W
Warning  
To avoid electric shock, do not execute the  
performance tests procedures unless the  
Meter is fully assembled.  
8. Repeat step 3 to verify that the ice bath temperature is  
at 0.0°C ±0.3°C.  
To ensure that the Meter is working properly and performs  
to specifications, use the following procedures. If the Meter  
fails this test, it needs calibration adjustment or repair.  
Calibration Adjustments  
Perform the following calibration adjustment procedures if  
the Meter fails the performance test.  
Multimeter  
Initial Steps  
1. Remove any input signals to the Meter.  
Note  
The following performance test is for all functions  
except for temperature. Temperature performance  
test follows this procedure.  
2. Remove the four screws on the back and separate the  
case bottom and case top.  
Notice that when you do so the battery remains in the  
case top and power to the Meter is disconnected.  
1. Referring to Table 3, put the Meter in the function and  
range shown for Test 1.  
Note  
2. Apply the input from the appropriate source to the [+]  
and COM jacks on the Meter. The reading on the  
display should be within the MINIMUM and MAXIMUM  
values shown in Table 3.  
To avoid stretching or bending the battery  
contacts, connect leads to the base of the  
contacts as shown in Figure 4.  
3. Test the remaining functions and ranges. Repeat steps  
1 and 2 for test numbers 2 through 41.  
3. Observing correct polarity, connect a 9 V battery to the  
battery contacts using easy hook jumpers or alligator  
clip leads (see Figure 4).  
Temperature  
Multimeter  
Note  
Note  
The performance test for the other functions must  
be done before this test is done.  
The following calibration adjustment  
procedure is for all functions except for  
temperature. Temperature calibration  
adjustment follows this procedure.  
1. Connect the equipment as shown in Figure 3.  
2. Insert a mercury thermometer to the same depth as the  
thermocouple wire to verify that the ice bath  
temperature is 0.0°C.  
1. Set the calibrator for 0 V dc. Put the Meter in the 4.000  
V dc range.  
3. Short (or apply 0.0 mV) to the copper wires at the  
5700A Calibrator.  
2. Connect the calibrator to the [+] and COM jacks on the  
Meter.  
4. Verify that the Meter reads 0.0°C ±0.8°C.  
3. Apply an input of +4.000 V dc ±0.25%  
5. If this test fails, reposition the thermocouple wires and  
mercury thermometer in the ice bath and repeat steps  
3 and 4. If the Meter continues to fail, use steps 6  
through 8 to verify the temperature performance tests.  
The Meter display should read between 3.997-4.003 V.  
If it does not, adjust R4 as described in step 4 (see  
Figure 4).  
4. Adjust R4 (see Figure 4) so that the Meter display  
reads between 3.997 and 4.003 V.  
6. Remove the short applied in step 3.  
5. Proceed to adjust the Temperature function.

1. In the Automatic Selection mode, the Meter uses a low-impedance thermistor (~2.5k for circuit protection and load testing  
(referred to as low-Z input circuitry). When using the 5100B, 5500A, or 5700A to drive the Meter with high voltages, avoid an  
overload/current limit condition by gradually stepping the voltage up (waiting two seconds between each step) from 90.0 V,  
120.0 V, 180.0 V, and 350.0 V at 80 Hz each step.  
2. Calibrator 50divider override.  
3. The dc volts annunciator must be on.  
4. Conducting performance tests of the 400 , 4 k, 40 k, and 1 µF ranges (tests no. 22, 23, 24, 25, 26, 31, and 32) verifies  
that the discrete and integrated circuitry needed to support the other capacitance ranges are working within specifications.  
Therefore, the tests indirectly verify that the Meter will meet specification in the 10 µF, 100 µF, 1000 µF, and 10,000 µF  
ranges.

4. Connect the other end of the thermocouple wire to the  
Meter using a Fluke 80AK Adapter Plug (see Figure 6).  
Allow the instrument reading to settle.

Note  
Adjust DC voltage (R4) before adjusting  
temperature (R38).  
5. Adjust R38 so that the Meter display has the same  
reading of the ice bath temperature.  
The following describes three temperature calibration  
procedures:  
Lag Bath Calibration  
Calibrating at room temperature. Use this procedure if  
it is not necessary to optimize the Meter’s performance.  
The following adjustment optimizes the Meter’s  
performance at room temperature using a specific  
thermocouple.  
Calibrating in an ice bath. Use this procedure to  
optimize the Meter’s performance at around 0.0°C.  
Calibrating in a lag bath. Use this procedure to  
optimize the Meter’s performance at room temperature.  
1. Put the Meter in the temperature function and °C  
mode.  
2. Insert a thermocouple in a lag bath (see Figure 6).  
Room Temperature Calibration  
The following procedure allows you to make the calibration  
adjustment at room temperature.  
3. Insert a mercury thermometer to the same depth as the  
thermocouple wire to verify that the lag bath  
temperature is at room temperature  
4. Connect the other end of the thermocouple wire to the  
Meter using an 80AK Adapter Plug(see Figure 6).  
Allow the instrument reading to settle.  
1. Allow the Meter to stabilize at room temperature. After  
the temperature stabilizes, do not touch the COM jack.  
2. Turn to temperature function and °C mode.  
5. Adjust R38 so that the Meter display has the same  
reading of the lag bath thermometer.  
3. Observing the correct polarity, connect a copper short  
across the input jacks of the Meter (see Figure 5).  
Replacement Parts  
Replacement parts are listed in Table 4 and shown in  
Figure 1.  
4. Using a temperature probe with the appropriate Meter  
(Fluke 45 or equivalent), measure the temperature of  
the COM input jack (see Figure 5). Be sure to place the  
probe on the COM closest to the pca.  
Table 4. Replacement Parts  
5. Adjust R38 so the Meter display is the same as the  
temperature probe reading.
